Serial No. 3235,4128.

To all ii /mm it may. cm crrrn: Be it known that 1, Arinicn'r ROSENBAUM,

a citizen oi the United States, residing in New York, in the borough of Manhattan, county and State of New York, have invented certain new and useful l n'iprovements in Clutches for Scarf-Pins, of which the following is a specification.

- This invention relates to certain improve ments iii-clutches t'or scarf-pins, which, instead of being applied as a separate. device to the shank ol' the scarf-pin, is attached to the under-side ol' the scarf near the point where the scarf-pin is to he inserted, so as to be always ready for use in clamping the scarf-pin and not liable to he dropped and lost.

The in vontion consists of a clutch for scarf-pins which is composed of two flat pieces, a main-piece and a clamping-piece fulcrumcd thereto, hoth pieces heing piovided with means for attaching them to a scarflthe main-piece having a socket open at the side for receiving the scarf-pin while the tulcrun'ied section is provided with a camshaped portion adjacent to the socket For clamping the scarf-pin lirinly in the socket of the main-piece and retaining it securely in position therein.

In the accompanying drawings, figure 1 represents a i'rinit-elevation oi my improved clutch lor scarfnns showing the pin inserted and clamped by the same, Fig. 2 also a iront-clevation, with the movahle clamping piece in open position so as to permit the in sertion or removal of the scarf-pin, Fig. 3 is a vertical longitudinal sect-ion through the clutch, and Fig. 4 is a detail section through the socket and clamping-picce, drawn on a larger scale.

Similar letters oi" reference indicate corresponding parts. i

My improved clutch or fastener i'or scaripins consists of a main-piece (L, which is made oi [lat sheet-metal and ot a clamping piece I), which is also made of liat sheet-metal, and which is fulcrumed to the main-piece a at c". From the body of the main-piece is relerahly punched up asmall portion which is hent over so as to form a socket (l, which is open at the side for permitting the quick insertion oi the shank of the scarf-pin. The l'uh-rumml clamping piece is provided at its inner end, adjacent to the open side of the socket, with an eccentric cam-portion I) that is bent up or thickened at the inner edge sons to close the side-opening of the socket d after the shank of the pin is inserted. As soon as the scarf-pin inserted into the socket the claniping-piece is turned and more-d in line with the mainnew so that its eccentric edge or cam chnnps the pin firmly into the socket and prevents there "the re moval or accidental detachment of the pin from. the scarf The greater the pull exerted on the shank of the scarf-pin, the greater will he the binding action of the eccentric cam on the same.

The outer ends of the lllttil'l-PiBQQ o and clamping-piece i) are provided with prongs u and I) having sharp points that are forced 7 into the under-side oi the scarf, below the point where the scarf-pin is inserted, by placing the clamping-piece and main-piece at an angle towardseech other and then forcing them into alinelnent with each. other whereby the prongs pierce the l'ahric'of the scarf. For inserting the shank of the scarfpin into the clutch the clamping-piece is inovedon its pivot in upward direction, the shank then inserted into the socket of the inain-picce and then locked into the socket hy moving the cam oi' the clamping piece into closed position. The pin is then'se-' enrol held in position against detaching or removal. in place oi piercing the under side of the scari Irv the pointed prongs, the main and clampingpieces may he sewed on permanently to the snarl, For which purpose small holes are provided in the outer ends-of the pieces for the passage l' the ni-iedle and thread.

'lhe main-piece is provided with an in dentation 'i and the pivoted clamping piece; with a slight raise i, the indentation arid raise registering with each other and serving 95 to hold the parts in hicked position so as to prevent the :u'cidental opening oi the pivoted.

clamping-piece into released position. My improved clutch for scarhpins can he made from gold, mckelor silver-plated 100 sheetemetal, and forms a (heap yet ethwiivc attachmentfor holding scarf-pins rt-liahiv in position on them-art's.

.llaving thus descrihed .my invention. it

tilttlll'l as new and desire to secure lay Letters 105 Patent:

1. A clutch lor scari-pins consisting of a main-piece. and a clamping piece pivoted thereto the main piece being provided with a socket open at the side for receiving the 110 shank oi" the scarf-pin and the clamping piece with an eccentric cam tor tightifv hold ing the shank in the socket, both main-piece and clamping-piece being provided with means forett'aehing said pieces to the scarf. 2. A clutch for scarf-pins consisting of a main-piece and a c1 an1ping-piec e pivoted thereto, the main-piece being provided with n socket open at the side for receiving the shank of the scarf-pin and the clampingpieee with a cam for tightly holding the 10 shank in the-socket, both the main and clamping pieces having pointed prongs at the ends In testimony, that I claim the foregoing as my invention, 1 have signed my name in presence of two subscribing witnesses.
